The new roadster is delayed, not abandoned. It's known to be in active development and is very likely to be demoed this year. Wrong timeline but not abandoned.
The Tesla semi is on the road daily and the factory to build large quantities is almost complete. They're hosting a "factory inauguration" event next month. Certainly not abandoned.
Tesla has already committed to replacing hardware as necessary on cars that purchased FSD in the past so that they can run unsupervised as promised, after Tesla has unsupervised FSD working. Certainly the timeline was wrong but again, clearly not abandoned.
New Roadster is over six years late and has basically gone silent at this point. Maybe it'll still come, just extremely late, but I'm very skeptical.
Semi might be real, we'll see.
If cars that were built with AP2/2.5/3 get upgraded to unsupervised FSD, I'll eat my hat. They don't even know what hardware will be needed yet and some of those cars are now a decade old.
